Trading System

[Kyran]

I am going to make a trading system for a game that I am working on and would like to know the best way to do it.
I'm guess that a listbox would be the way to go. There will be a listbox for every location and every character, when a character pick up an object from a location that object is moved from the location's listbox to the character's listbox.

I'm having problems with how to use listboxes.

Say I have a listbox called myData.

myData.addItem("Flower");
myData.addItem("Pen");
myData.addItem("Herb");
myData.addItem("Herb");
myData.addItem("Herb");

I'll add five items, three herbs, a flower and a pen. That works fine, the five items show up great.
Yet now say I want to remove one Herb from the listbox.
myData.removeItem("Herb")
That doesn't work.


if (notData = hasa”herb”) {
myData.removeItem("Herb")
myData.addItem("Herb")
}
Also I'll need to know how to use IF THEN statements and how to swap objects.
I know about removeItemAt and how to use it, but I don't want to be forced to use numbers.

The listbox is not going to be shown. Is it able to do this, or is there something that would work better?
